As i mentioned it seems like the helm side of the boat is flexing, maybe its more of my chair moving then the hull? Last weekend i drove around for a bit with the walk through window closed (yes open bow) and as i went through some small waves the gap where the two windows meet moves about a quarter of an inch or so, more at the top then toward the bottom. I also hit a decent wave, not purposely, and the tow windows smacked together. I almost never drive with the window closed so hadn't noticed before. Does this seem excessive? Also, in your boat when you close the window is there a 3/8 inch or so gap between the window panes?
